PRESSER MEMBER FCR FLL'ER MACHINES.

Application led June 19,

This invention relates to a presser member for the lier `frameot1 rovingmachine; and has for its object to construct ia presser member' so thatits etective weight may be varied to bal-ance the fiier :trame to whichit is attached and prevent vibration thereof during rapid rotation.

A further object ot the invention is to pro vide a presser member thatis adapted to carry a weight which may be varied to adjust its effectiveweight.

A still further object of the invention is to provide the presser memberwith a hollowshank in which is lodged weighting means variable to adjustthe effective weight of the presser member.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation illustrating a lier frame with the improvedpresser mem ber attached thereto and the yarn package is illustrated indotted lines in the relative position which it assumes on the rovingmachine.

Figure 2 is a partial sectional side elevation of the presser showing ahollow shank with a weight therein.

Figure 3 is a sectional plan view of the foot portion of the pressertaken on line 3-3 of Figure 1.

Figure 4 is a ragmental side elevation partly in section of the pressermember showing weighting means of a dierent form in the hollow shank.

It is found in practice that new flier frames and their presser membersare of such weight that the presser which is attached to one of the legsof the flier frame, compensates for the weight of the opposite heavierleg of the flier so as to balance the flier during its rapid rotationabout the yarn package. However, when repair is needed or a new pressermember is required, it is found very difficult to so force the pressermember and nish the same as to perfectly balance the iiier thus causingvibration and excessive wear to the iiier and spindle and making anundesirable noise in the operation of the roving machine. l-leretotore,the presser' members have been made solid but in order to provide astructure which may be easily varied in weight, I have found it 1926.Serial No. 117,189.

desirable to make the shank-fot the presser member hollow and to placein; this hollowv shank a weight in suiiicient quantity to balance thefler` traine and prevent excessive vibration ot the same; and thefollowing is :a detailed kdescription of the present fembodiment of thisinvention for obtaining these advantageous results:-

VVith reference to the drawings, 10 designates a yarn package which isillustrated in dotted lines, on the spindle of which is mount-ed theusual inverted U-shaped flier frame 11 having a solid leg- 12, a hollow.leg 13 through which the yarn 14 is led from the .draft rolls (notshown). l On this hollow leg 13 of the iier there 1s mounted a pressermember comprising a shank portion 15 having a toot 16 with an eye 17through which the yarn 14 is guided onto the yarn package, it beingunderstood that the flier frame with the presser member revolves severalhundred revolutions a minute and at the same time has a longitudinal ornp-and-down movement relative to the package for suitably guiding theyarn thereon.

rlhe shank 15 of the presser member is formed hollow, as illustrated inFigure 2, and is provided with weighting means 18 which may be in theform of an elongated core of any suitable material. This lead core beingeasily cut off to provide the proper amount of weight and this weightingmeans may be in the form of lead shot 19, as illustrated in Figure 4, bymeans of which any slight deficiency may be made up to obtain theeffective weight of the presser member desired. At the upper end of thisshank a threaded plug 20 is provided for closing the shank to prevententrance of dirt or other foreign matter which might affect the balanceof the presser member.

From each end of the shank, arms 21 and 22 extend to be bent about andembrace the leg 13 of the flier frame to secure the presser memberthereto.

It will thus be seen that I have provided a presser member the e'ectiveWeight of which may be varied within reasonable limits to accuratelybalance the flier during its rapid rotation and thus eliminate thevibration caused from an unevenly balanced flier trame, itbeingunderstood that large numbers of these fliers are in operation on aroving machine and then any vibration is many times multiplied.

The foregoing description is directed( solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention beingdened and limited only by the termsof the appended claims.

I claim:

l; A presser member for a fiier frame comprising a hollow shank, a footportion attached thereto, Weighting means in said hollow shank adaptedto be varied to regulate the effective weight of the presser, and meansfor attaching said presser member to a flier frame. e

2. In combination with a Hier frame, a presser member having a hollowshank attached to one of 'the legs thereof, a foot at the end of saidshank having means for guiding the yarn, and weighting means in saidhollow shank adapted to be varied to adjust the weight of said member tobalance the iiier frame.

3. In combination with a flier frame, a presser member having a hollowshank, arms adjacent each end thereof embracing said flier frame, apresser foot attached to said shank having a yarn guiding opening, and aweight in said hollow shank sufcient to balance the flier frame andprevent vibration thereof while rotating.

4L. A presser member for a flier frame comprising a hollow shank, a footportion attached thereto, weighting means in said hollow shank adaptedto be varied to regulate the effective weight of the presser, a plug forclosing the end of said hollow shank, and means for attaching saidpresser member to a flier frame.

In testimony whereof I aIiX my signature.

WILLIAM J. MAHER.
